Precautions

1. Be sure to avoid a long charge. When charging, please make the instrument in the off state, you can make the charging time reduce, and then charging in the on state, the instrument's sensor may be subject to the difference between the charger (or charging environment differences), in severe cases, the instrument may appear displaying the value that is not accurate or even in the alarm situation.
2. Instrument in the power is turned off after the automatic shutdown, the normal charging time of 3 to 6 hours or so, try not to make the instrument charge in more than 6 hours to protect the battery part of the effective life of the battery.
3. After the instrument is fully charged, the continuous working time is related to the opening and alarm of the pump. (Due to open the pump, the alarm when the flash, vibration, sound need additional power consumption, has been alarm state, working time down to the original 1/2 to 1/3).
4. Always use the instrument in a corrosive environment.
5. Be sure to avoid contact with the instrument.
6. It is advisable to unplug the power cord for a long time, or to charge the battery once every 1 to 2 months to protect the battery's normal life.
7. If you use the process, the crash or can not boot, in the back of the instrument below a small hole, with the top of the needle, you can.
8. Please be sure that the gas indicators are normal in the case of boot, after the start of the instrument after the initialization is completed to bring the place to detect the gas.
9. To use the record storage function, it is best to start the device after the initialization is not completed before entering the menu calibration time to prevent the time to read the record chaos. Otherwise there is no need to correct the time.
